It's Easy Being Green

There are thousands of sites spread across our globe where groundwater supplies have been contaminated due to dirty factories, military installations and the dumping of toxic waste.  These so-called superfund sites are left to sit until the expensive cleanup operation can get underway and have undoubtedly a harmful impact on our environment and supplies of drinking water.  But one scientist at Rice University has come up with an amazing solution, one that could leave at least part of our planet gleaming!

Chemical engineer Michael Wong developed a gold detergent that is amazing effective at cleaning up water contaminated with toxic waste.  No, this isn’t a hundred dollar bottle of soap that the likes of Paris Hilton would bathe in twice daily!  Typically cleanup of these sites containing the cancer causing chemicals TCE and PCE costs millions of dollars and it never really gets rid of the problem.  TCE is an industrial solvent used to clean greasy machinery and while it smells sweet, the after-affects are anything but.  The current cleanup method is simply a process that moves the chemicals to another spot.  The federal government has suggested that just to clean up the 1,400 military sites would cost $5 Billion.

Wong realized he could combine gold particles (molecule sized) with palladium (another metal) and sprinkle the resulting mixture over contaminated water.  What happened was pure genius!  The gold detergent broke down the TCE and PCE and turned them into a more eco-friendly gas, ethane, and chloride salt.  The gold detergent works about 100 times faster than the current groundwater cleanup method which involves pumping water through charcoal filters to remove the TCE and PCE.  Wong and his partners at Rice will now deploy the system at an actual cleanup site to see just how effective and cost-efficient their gold detergent can be.
